Interrupt Mask Register
Each interrupt source can generate an interrupt signal on port INT
(characteristics of the output stage are defined by register IPC). A “1”
in a bit position of IMR(5:0) sets the mask active for the interrupt
status in ISR(5:0). Masked interrupt statuses neither generate a
signal on INT, nor are they visible in register GIS. Moreover, they are
– not displayed in the Interrupt Status Register if bit GCR.VIS is
– displayed in the Interrupt Status Register if bit GCR.VIS is set
After reset, all interrupts are disabled.
